Definitions
- the invention relates to a roller conveyor for handling roofing tiles, particularly of the beaver-tail type.
- Prior art includes motorized conveyors constituted by a plurality of mutually parallel rollers, which are used to transfer clay-based construction components and the like through their production cycle.
- roofing tiles having a rectangular surface which is variously shaped or curved and used to cover roofs are important among clay-based construction components.
- roofing tiles and particularly those known as "beaver-tail'' or “Biber'' tiles have, on their lower surface, one or more protruding teeth which are required to allow the mutual anchoring of the tiles during the formation of a roof.
- the plates Moreover, during their travel inside the kilns for firing the clay-based components the plates necessarily absorb heat and therefore require a higher energy expenditure to reach and maintain certain temperatures.
- an object of the present invention is to achieve this aim with a structure which is simple, relatively easy to provide in practice, safe in use, effective in operation and relatively low in cost.
- the present roller conveyor for handling roofing tiles, particularly of the beaver-tail type having at least one protruding tooth at at least one end of their lower face, characterized in that a plurality of pairs of rings are correspondingly distributed along each roller of the conveyor, the relative spacing of the rings being substantially equal to the width of said at least one tooth for centering and guiding the tiles, the lower surface of said tiles resting on the crests of the rings.
- the reference numeral 1 generally designates a roller conveyor according to the invention for handling roofing tiles 2, particularly of the beaver-tail type and having at least one protruding tooth.
- the tiles 2 have, at one end of the lower face 3, two protruding teeth 4 which are conveniently spaced one another.
- the rollers 5 of the conveyor 1 are parallel one another and each one has a plurality of pairs of rings 7 distributed thereon; the rings are arranged at a mutual distance corresponding to the width of the teeth 4.
- the rings of two adjacent pairs 6 have a pitch 8 which substantially corresponds to the distance between the two teeth 4.
- Each tooth 4 engages each adjacent pair 6 of rings 7, while the lower surface 3 of the roofing tile 2 rests on the crests of the rings.
- the rings 7 can be made of the same material as the rollers 5 or, as an alternative, they can be made of a different material and be rigidly coupled to the corresponding roller by cementing and/or fixing pins, not shown.
- the rings 7 and the rollers 5 are made of silicon carbide or, as an alternative, of a material such as steel or, as an alternative, of a ceramic material, a refractory material or a material such as superalloys based on nickel and cobalt.
- the teeth 4 of each roofing tile 2 can extend along most of the lower surface 3 so as to engage more than one corresponding pair of rings of rollers 5 to better guide the roofing tile 2 along its path on the conveyor 1.
